Note: The FERS calculation of the growth of your future contributions and earnings includes the effect of Agency Automatic (1%) and Matching Contributions.  Therefore, if you are a newly hired FERS employee participating in the TSP but not yet eligible for agency contributions, the estimated growth of your future contributions and earnings will be overstated because of the period during which you receive no agency contributions.  You may wish to recalculate your projections once you become eligible.  For CSRS employees and members of the uniformed services, the calculation of the growth of your future contributions and earnings does not add any agency or service contributions.

1. You may begin contributing to the TSP (through payroll contributions) when you are hired.  However, new FERS employees must serve a waiting period before agency contributions begin.  (For more information on eligibility for agency contributions, see "Participating in the TSP" in TSP Features (for civilians or uniformed services).

2. In addition to the percentage contribution limits in the contribution limits chart, the maximum amount of your own basic pay that you can contribute to the TSP is also limited by the IRS.  Do not enter a percentage that will result in an amount exceeding the IRS annual limit.  TSP employee contribution limits and IRS limits will increase each year.

3. The amount you can contribute to the TSP in catch-up contributions is also limited by the IRS.  Do not enter a dollar amount that will result in an amount exceeding the IRS limit.  These limits change each year.
